Kua tāruatia ki te papatopenga
3x+4=\frac{9}{2}
Whakawehea ngā taha e rua ki te 2.
3x=\frac{9}{2}-4
Tangohia te 4 mai i ngā taha e rua.
3x=\frac{9}{2}-\frac{8}{2}
Me tahuri te 4 ki te hautau \frac{8}{2}.
3x=\frac{9-8}{2}
Tā te mea he rite te tauraro o \frac{9}{2} me \frac{8}{2}, me tango rāua mā te tango i ō raua taurunga.
3x=\frac{1}{2}
Tangohia te 8 i te 9, ka 1.
x=\frac{\frac{1}{2}}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{1}{2\times 3}
Tuhia te \frac{\frac{1}{2}}{3} hei hautanga kotahi.
x=\frac{1}{6}
Whakareatia te 2 ki te 3, ka 6.
